Dalstroem's Dragon Orchid problems — and how to fix them
Dalstroem's Dragon Orchid (Dracula dalstroemii) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Temperature stress above 20°C
Dracula orchids are highly cold-dependent; sustained daytime temperatures above 20°C cause leaf yellowing, root dieback, and failure to flower. A cool growing space with active chilling (air conditioning, wine cooler-style cabinets, or a cool greenhouse) is essential in warm climates.
Flower spike trapped inside pot
Pendant spikes grow downward and cannot emerge from solid-sided pots, leading to aborted or deformed flowers. Always use slatted baskets, mesh pots, or open-sided mounts so spikes exit freely through the gaps.
Botrytis on flowers and leaves
The extremely high humidity needed by Dracula makes it very susceptible to grey mould. Keep air moving with small fans at all times, remove spent flowers immediately, and treat any grey fuzzy patches promptly with a copper-based or iprodione fungicide.
